NGS Finds a Real-Time Solution
An Iowa RTN contributes to the National Geodetic Survey’s Geoid Slope Validation Survey of 2014. The gravimetric geoid model will become the zero-height surface for the new geopotential reference frame, which will replace the North American Vertical Datum (NAVD 88) in 2022. The Geoid Slope Validation Survey of 2014 (GSVS14) is the second survey conducted...

Quarry Monitoring
In Slovenia, a team monitored slope stability in an open-pit quarry using a classic, optical precise level and Invar rod. Editor’s note: Cost-benefit analysis dictates that, for open-pit mines and quarries, steep slopes allow for the most efficient extraction of resources but at an increased risk of slope failures. This adapted paper outlines an example...
Stretching Surveyors across the Water
Surveying the Gorgon Jetty Project on Barrow Island off Western Australia involved integrating structural, mechanical, and hydrographic surveying technologies and skills. Barrow Island is described by some as Australia’s answer to the Galapagos Islands. The 202 km2 (78 mi2) island and its surrounding ocean are home to diverse and unique fauna, including marsupials, reptiles, sea...
